Abstract: A gastronomy tube (20) is a flexible tubular member (21) having on a first e nd (22) thereof an improved energy absorbent internal retaining member (23) which pr ovides for less patient trauma during emplacement and subsequent percutaneous removal, while almost entirely avoiding either separation of the internal retaining member, i.e., the bumper, or its acute displacement. The energy absorbing internal retaining member (23) has a hollow body portion (25) with two resiliently reversible physical forms or shapes, toroidal-like, and goblet-like connected to a foreshortened hollow axial stem portion that is a ttached to or integrally made with the inward end of the flexible tube. The internal retai ning member is made in the toroidal-like form. During intentional removal, when under press ure against the stomach mucosa, the internal retaining member snaps into the unrolled, goble t-like shape and pulls smoothly out through the stoma tract.

Abstract: A method of programming an interactive scenario on a multitrack storage media (4) is disclosed. The interactive scenario includes a number of time-synchronized frames on separable data streams which are related in content to one another. The interactive scenario is played back on an apparatus (2) which includes means for selectively retrieving the data streams at a given time. A decision-making goal is defined for the interactive scenario. Once the goal has been defined, a set of rules is developed, preferably using knowledge derived from an expert, which lead to the defined goal. The rules relate hierarchically whereby the conclusions of at least some of the rules are premises for other rules. The rules also logically relate whereby the conclusion of a final rule or rules corresponds to the decision-making goal. If the rules require premises to be obtained, queries are generated to interactively ask for the premises.

Abstract: In accordance with the present invention, there is provided a guidewire for navigating through body vessels so as to deliver a balloon catheter or the like. The guidewire has an elongated core wire having distal and proximal ends and a longitudinal axis extending therebetween. The guidewire also has a coiled spring surrounding the distal end of the core wire. Lastly, the guidewire includes a tube surrounding the core wire proximal to the coiled spring. The tube is able to slide back and forth with respect to the longitudinal axis of the core wire. The tube has a distal end and a proximal end. The distal end of the tube is coupled the proximal end of the coil so that as the tube slides along the longitudinal axis of the core wire, the length of the coiled spring changes, thereby changing the flexibility of the coil.

Granted: 2006-07-18
Abstract: A method and apparatus are provided for providing an ion transmission device or interface between an ion source and a spectrometer. The ion transmission device can include a multipole rod set and includes a damping gas, to damp spatial and energy spreads of ions generated by an ion source. The multipole rod set has the effect of guiding the ions along an ion path, so that they can be directed into the inlet of a mass spectrometer. The invention has particular application to MALDI (matrix-assisted laser desorption/ionization) ion sources, which produce a small supersonic jet or matrix molecules and ions, which is non-directional, and can have ions travelling in all available directions from the source and having a wide range of energy spreads. The ion transmission device can substantially spread out the generated ions along an ion axis. Consequently, a number of pulses of ions can be delivered to the time-of-flight or other spectrometer, for each cycle of the spectrometer.

Title: Power circuit for transferring energy by alternately switching winding circuits of a transformer at high speed
Inventor: HISANAGA KOJI
IPC: H02M7/12
Filed: 1998-05-28
Granted: 2000-09-26
Abstract: In a power supply unit, AC energy is converted to DC energy and stored into a first capacitor to which a first winding of a transformer is connected. An anti-parallel circuit of a first transistor and a diode is connected between the first capacitor and the first winding. An anti-parallel circuit of a second transistor and a diode is connected between a second winding of the transformer and a second, battery-charging capacitor. A current is induced in a third winding of the transformer for charging a third capacitor when a current is produced in the first winding in a particular direction or when energy stored in the second winding is released into the third winding. The first and second transistors are alternately switched on so that energy is transferred from the first capacitor to the second and third capacitors when the AC energy is normal and energy is transferred from the battery to the third capacitor when the AC energy fails.
